1. Budget : max rm2000
2. Usage : for my sister who just finished spm, basically for normal usage, online streaming, youtubing, office works, not a gamer.
3. Requirements (display size, battery life, weight etc) : 13", <2kg, 4gb ram (upgradeable to 8gb), 500gb i think is sufficient, processor and graphic card doesnt really matter i think..

If lets say i buy the 4gb ram and add another 4gb, will it void warranty?
